Abstract: FIELD: rubber industry. SUBSTANCE: aim of invention consists in obtaining a rubber stock using additives of non-vulcanized rubber-cord waste and simultaneously increasing performance of produced objects, for example, pneumatic tires resulted from additional reinforcement and raise of elasticity and rigidity characteristics of tires. As additives, of use are wastes of polyamide and viscose rubber- covered non-vulcanized cords that are crushed and treated on rotor pulverizer of tire-cut type. Material is twice passed through 6-8- mm clearance between mobile and stationary knives, then processed on two crushing rollers by means of 3-4-fold passing through 0.35- 0.65-mm gap. The thus prepared sheet 3.5-6.5 mm thick is crushed on a rotor crusher of noodles-cut type with 0.2-0.3 mm gap between mobile slope knives and a stationary one mounted on the drum. After additional processing and crushing on crushing rollers and on noodles-cut-type crusher, crushed mass is used as additives in amount of 2-10 weight parts per 100 weight parts of the rubber. To enhance effect of orientation of threads and fibers along the sheet, one of the second couple of rollers is made smooth. Crushing of the sheet on noodles-cut-type crusher is performed transversely to threads oriented by "calender effect" when processing on crush rollers. EFFECT: improved quality of produce; reduced cost due to utilized waste.

Abstract: FIELD: designs of rectifying towers. SUBSTANCE: sheet steel cylinder of rectifying tower has vertical tubular body whose hollow accommodates packing with trays. Packing is formed of casings arranged in stories and square in cross-section with internal size of side D in plane perpendicular to body vertical axis. Each casing is turned through 90 deg relative to vertical axis and to adjacent casing. Mounted vertically in each casing are trays in the form of corrugated plates of constant height b, corrugation constant height c and constant corrugation pitch h, constant angle "α" of corrugation inclination relative to body vertical axis equal to 30-60 deg and constant length l equal to size of side D to ensure high unification of plates and packing as a whole. Plate height b equals casing height. Plates after installation into casing are engageable with one another by tops of corrugations inclined in adjacent plates in mutually opposite directions. Body is embraced with shell from heat- insulating material. Secured to ends of the body are upper and lower circular cover plates having fastening member for locking in body extreme casings. Fastening member may be made, for instance, in the form of flange facing radially inside which partially covers the end of respective casing. To ensure tightness of sheet steel cylinder when it is joined with adjacent sheet steel cylinder, this sheet steel cylinder is screwed with internal thread on the external thread of cover plate of the adjacent sheet steel cylinder, and sealing packing is installed between cover plates. To improve locking of extreme casings, sheet steel cylinder is furnished with spacer made in the form of vertical plates tied to each other by their middle parts. Vertical plates form crosswise, in plan, member whose end sections are located in angle zones of body cross-section. EFFECT: higher efficiency. 6 cl, 5 dwg

Title: Methods for predicting board test coverage
Inventor: PARKER KENNETH P
IPC: G01R31/28
Filed: 2003-05-09
Abstract: Disclosed are methods for predicting board test coverage. In one method, board test coverage is predicted by enumerating potentially defective properties for a board design; determining how each of a number of potential test technologies could be applied to the board design; and predicting board test coverage for one or more combinations of the potential test technologies. Board test coverage is predicted for a combination of potential test technologies by, for each potentially defective property enumerated, generating a property score that is indicative of whether a potential test technology could test for the potentially defective property; and combining property scores to predict board test coverage for the combination of potential test technologies.
